Eye health has profound and widespread implications for many aspects of life, health, sustainable devel opment, and the economy. Yet many populations do not have access to goodquality, affordable eye care.Worldwide there are more than 250 million people living with vision impairment, among whom 36 million are blind. 1 In addition, over a billion people have near vision impairment, simply because they do not have a pair of reading spectacles. Eye conditions and the vision impairment they cause affect all stages of life, with increasing burden with age. Over the next 30 years, ageing and growth of the global population will lead to a tripling of people affected, with 700 million vision impaired and 115 million of these blind. 1 Critically, 80% of this sight loss is preventable or treatable, and 90% occurs in lowincome and middleincome countries (LMICs). Sight loss has substantial economic implications for affected individuals, families, and communities, with global estimates of annual costs exceeding US$ 3 trillion. 2 Good vision facilitates many activities of daily life and improves education and employment opportunities. Available good quality evidence shows that improved eye health offers the potential to advance progress towards the Sustainable Development Goals (SDGs), including those pertaining to poverty, hunger, good health and wellbeing, education, gender equality, and decent work. [3][4][5] Sight loss has many causes that require a range of promotive, preventive, curative, and rehabilitative inter ventions. Cataract, refractive error, agerelated macular degeneration (AMD), glaucoma, corneal opacity, and diabetic retinopathy are responsible for the majority of global vision impairment. 6 While interventions are available for these, there is a pressing need for research to improve detection, therapeutic efficacy, and implementation. Moreover, many of these interventions remain out of reach for millions living in underserved regions in LMICs as well as disadvantaged populations in highincome countries.In the quest to achieve universal eye health, a critical obstacle is the major shortage and maldistribution of appropriately trained personnel, particularly in Africa and rural areas within LMICs in other regions.
